How do I straighten a crooked photo online for free?

Open PixKit's Straighten tool, drag the Angle slider between -45° and +45° in 0.1° steps until the horizon is level, or tap the -90°/+90° buttons for quarter-turns, then click Apply. The canvas grows to fit and the exposed corners stay transparent. It runs 100% in your browser — free, no upload.

A private image toolkit, not just a watermark remover

Clean the Gemini sparkle, then finish the job — crop, resize, convert and adjust without uploading a single pixel.

Lossless watermark removal

Reverse-alpha math restores the true pixels under the Gemini logo — no blur, no AI guesswork.

Crop & resize

Crop to any aspect ratio with draggable handles, then resize to exact pixels or quick scales.

Convert & compress

Export to PNG, JPG or WebP with a quality slider and a live file-size estimate.

100% private

Every tool runs locally with undo/redo. Nothing is uploaded — it even works offline.

Straighten or rotate in 3 steps

Fine angles, quarter-turns, or both — with transparent corners and full undo.

Set your angle

Drag the Angle slider from -45° to +45° in 0.1° steps to level a horizon, or tap the ⟲ -90° / ⟳ +90° buttons for clean quarter-turns — combine both freely.

Check the readout

The label shows the exact total, like "+1.3° (+91.3° total)". Tap 0° or Reset to clear everything and start over before committing.

Apply and export

Click Apply — PixKit enlarges the canvas to fit the rotated image, keeps the corners transparent, and reports the new size. Export as PNG or WebP to preserve transparency.

What people straighten and rotate

Tilted horizons

Ocean, skyline and landscape shots taken in a hurry rarely sit level. A degree or two on the slider makes them look deliberate again.

Sideways phone photos

Photos that import rotated from a phone or camera get fixed with one tap of the +90° or -90° button — no quality loss on quarter-turns.

Scanned documents and receipts

Scans and photographed paperwork are almost never square. Fine 0.1° steps let you align text lines perfectly before saving or converting to PDF.

Product photos

Slightly rotated packshots read as sloppy in a listing. Level the product's edges against the frame for a cleaner, more professional look.

Creative dutch angles

Rotation isn't only for fixing — add a deliberate 10–15° tilt for dynamic social graphics, then crop to taste.

Frequently asked questions

Common questions about rotating and straightening images in PixKit.

Does straightening my photo happen on my device or in the cloud?+
Entirely on your device. The rotation is computed 100% locally in your browser with the canvas API — there is no upload, no cloud, and no account required.
How do I straighten a crooked photo?+
Open the Straighten tool and drag the Angle slider until the horizon looks level (you can fine-tune to 0.1°), then click Apply.
Can I rotate by exactly 90 degrees?+
Yes. Use the -90° and +90° quick buttons. You can even combine a quarter-turn with the slider to reach any angle you need — the label shows the running total.
What happens to the corners after rotating at an angle?+
PixKit enlarges the canvas to fit the full rotated image and fills the newly exposed corners with transparency. Export as PNG or WebP to keep the transparent areas, or crop afterward.
Will rotating change my image's dimensions?+
At non-right angles, yes — the canvas expands to the rotated image's bounding box so nothing is cut off, and the status line reports the exact new width and height in pixels.
Does rotating lose image quality?+
Pure ±90° quarter-turns remap pixels one-to-one with no blurring. Arbitrary angles are resampled once with high-quality smoothing, so apply your final angle in a single step rather than several small ones.
Can I undo a rotation?+
Yes. Every rotation is undoable, so you can experiment freely and step back with Undo if you change your mind.

Rotate and straighten photos without uploading anything

Crooked horizons and tilted shots are easy to fix. Drag the angle slider to nudge your image between -45° and +45° for fine straightening, or tap the quick buttons for clean 90° turns. Every adjustment happens on your own machine — your photo is never uploaded, stored, or seen by anyone but you.

Straighten a crooked horizon

Use the angle slider for precise tilts down to a tenth of a degree. When you apply, PixKit recomputes the bounding box so the whole rotated image fits, and fills the exposed corners with transparency — perfect for PNGs or for cropping afterward. The status line even reports the new pixel dimensions.

Quick 90° rotation — and any combination

Need to turn a sideways phone photo upright? The -90° and +90° buttons rotate in clean quarter-turns, and the readout shows your running total (say, "+2.5° (+92.5° total)") when you combine them with the slider. Hit Reset or the 0° button to start over at any time.

Private by design

PixKit runs entirely in your browser using the canvas API — no servers, no accounts, no tracking. Because there is no upload, rotation is instant even for large images, and your files stay completely private.
